With a 12th Gen Intel Core i3-1215U, 16GB of RAM and a 1TB SSD, the machine is targeted at office users, students and remote workers who need responsive multitasking and fast storage rather than high-end graphics.

Who It's For

This Inspiron 3520 is well suited to office professionals, students and home-office users who need a dependable 15.6in laptop for document work, video conferencing and web-based tools.
